TO ALL WHOM IT. MAY CONGERNL A Y I Beit known that I, NAPOLEON ffwmrn, of Cecil county, State of Maryland, have invented a new and useful Machine for Scaling Fish; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, forminga part of this specification, and in which-n Figure 1 is a top view, and l Figure 2 a central longitudinal section of the machine.

The nature of my invention consistsin the adaptation and employment of a revolving cylinder, of open ci lattice-work, having projecting metallic blades arranged upon its inner periphery and sides, for the purpose of removing the scales from fish. I cause the cylinder, when filled with fish, to revolvewithin a reservoir of water,

to prevent an accumulation or accretion of viscid matter therein.

The reservoir A, to contain the revolving cylinder, may be constructed in any suitable manner. Where it y `is convenient, I prefer lto p'lace itwhere a stream of running water may pass through it; otherwise, it is to `be so arranged as that the water may be frequently changed therein. y

In the accompanying drawings, A represents a tank or reservoir constructed of timber, provided with an apron or inclined shelf, B, at its front end, upon which the iis'h may he emptied from themachine. The tank is fitted with a cock for the discharge of water therefrom; or a simple hole, closed by a plug, C, may be pierced for the purpose. Upon lthie top of the tank A I Vplace a removable frame, D, whichiits closely and accurately over the sides of the tank, and rests upon cleats E secured thereto to support it.` 0n this frame, about `midway oi' its length, I place suitable journal-boxes, E, toy receive the journals of an axle, G,. which passes centrally-` through, and is rigidly connected with, a large" hollow cylinder, H. This cylinder is constructed of solid head or end pieces h k, united by transverse bars lc, secured to their rims, and forming an open framework.' Upcii-l"v y the inner face of each transverse bar c (or of one or moreoi` them) I secure a longinetallic blade, t', to project inwardly therefrom along its entire length. The edge of each vblade may be sharpened more or less, as shall'be found expedient. 'I also secure similar inwardly-projecting blades t' z' to the inner face of each head. The cyl*- inder 'H is furnished with au opening, M, extending its entire length, audclosed by a door, K, openingoutfV wardly upon suitable hinges. I provide, also, a separate and removable way or inclined sluice-bom-Ii, so made` as to rest pon the frame D and lit into the opening lM. The axle G oi' the machine may be providedfat one end with a crank, O, or with a pulley, R, to connect withany suitable motive power.` Where'4 a,crank,i0,'is employed, I employ a. catch-latch, P, to engage the crank and serve as a stop to prevent the cylinder from revolving whilst it is being illed or emptied.

The operation of my machine is briefly `as follows: Tank A containing lwater,ithe door'K ofthe cylinder being now thrown open, the detached sluice-hox L is placed upon the frame, with its open end resting upon the edge of the opening M in the cylinder, so as to form an inclined trough leading into 'the cylinder. The cylinder-` is held in thislposition, and prevented from revolving, by means of 'the catch P engaging with Vthe crank 0 of the cylinder. The iish to be scaled are thrown down the inclined way L into` `the cylinder until it is nearly" l filled. The inclined sluice or way L is then removed and the door Kef the cylinder closed, and the cylinder is then made to revolve rapidly by any suitable motive power. 'The l'ishare thrown-anddrawn, by centrifugal A f i J i `force, over the blades zz arranged upon its inner sides and eircumferencaiwhicli so engage therewith as to remove quickly the scales therefrom. The process. is facilitated by the wate'r in which the cylinder 4is partially 1 immersed, which carries oi the slime and detaches the `scales loosened by the scraping-blades. Sosoon as the` ish are sc alcd the cylinder is again secured by the catch'P, the door K thrown open, `and the 'clean fish thrown out upon the discharge-apron or shelf B of the tank.

The intervals between the slats Z: enclosing the cylinder must be increased or'ldiminished'according to thai sizeofl the sh to be scaled. As the cylinders and-their frames are detachable from -the' tank A, cylinders withI various openings mayl be employed with the same tank for treating different kinds andlszes `of'ish.

'.lhe blades Ir', instead of being formed in one unbroken length `from end to (end of the cylinder, may be" 1 formed of a. series of short blades, arranged in right lines and at different angles, and. their edges,I instead of being made straight, may be pointed or'rounded. l

Projecting wooden strips may serve as equivalents for the-metallic bludesz' in removing thesc'ale of some sh.

Having thus fully described my inveution, I claim therein as new, and desire to secure. by Letters Petent-- A hollow cylinder provided with blades or points, er their equivalents, projecting inwardly from it eircumference orl sides, when mede to revolve v:md otherwise adapted to the purpose of remoiing the seules from"- flsh, 'substantially :is herein set forth.

The foregoing speeieation of my improved machine for sealing fish, signed by me this twenty-second day of July, A. D. 1867. NAPOLEON BONAPARTE WHITE.
